commit bcf90cf446734e00e70b6c799d35dfc871f21b68
Author: Elad Alfassa <elad fedoraproject org>

    Notify and play a sound when rendering is complete
    
    Also reuse the render progress dialog at the end of rendering
    to allow the user to open the rendered movie in their default movie player.
    
    Fixes bug #650812
    
    Adds (soft) dependencies: libnotify with introspection support, pycanberra
